In a catalog, a backpack costs $40, a water bottle costs $10, and a pair of hiking boots costs $150. The store where Olen finds the
items has marked them all up by 20%. Olen went to that store so
that he could try on the shoes and measure the backpack before
buying. He normally wears a size 8, but found he needed an 8 72 in
that brand. If Olen has a 30% off coupon, how much will he be
charged for the hiking boots, before tax? Round to the nearest cent
if necessary.
